Sample with Purchase: Lancôme CILS BOOSTER XL

Birchbox Breakdown

Think of this lash primer as your mascara’s essential sidekick. Like Spanx under a favorite LBD, this clear base works behind the scenes, creating an even foundation that seriously amplifies your mascara’s impact. Micro fibers plump and lengthen lashes, helping even the shortest ones stand out, while Vitamin E nourishes and protects. But don’t take our word for it: Try it for yourself. For a limited time, you’ll receive a free sample with any full-size Lancôme mascara purchase.

How to Use

Apply one coat of Cils Booster XL to lashes. Allow to dry for 30 seconds, then apply your mascara of choice.
